I love GLaDOS so much. She is the definition of "passive aggressive", meanwhile she is also a robot and it's hilarious and genius. Plus you kinda just feel bad for her, you know? Mostly in Portal 2 but at least in Portal 2, she's not as lonely.
I feel like her original design is too often overlooked. I guess it's not as sleek and shiny as her Portal 2 appearance but it has a certain charm to it, I think. Tbh though her newer design would be a lot easier to make D:

First time making anything sci-fi-ish...hopefully things will go well!

In the process of making the arm pieces & cores at the moment. I'll upload photos once I make a little more progress on them.
